Description of the Related Art One of the methods for repairing an outer wall surface of a structure such as a building structure is to fix a rope (wire rope) on an upper part of the structure and provide a winder on the rope. A work gondola or the like is suspended and a winder is driven to move the work gondola or the like up and down along an outer wall surface.

A rope such as a hanging wire rope for suspending such a work gondola needs to be protruded from a parapet on the roof of the structure and fixed so that the work gondola can work without hitting an outer wall surface. Yes,
Conventionally, various rope supporting devices have been used.
As shown in (a) and (b), two different types of rope supporting devices (usually, one is called a projecting beam and the other is called a free hook) according to the thickness of the parapet 2 on the roof of the structure 1. ) Is used to perform work on the outer wall surface 3.

[0004] First, a rope supporting device (usually referred to as a projecting beam) 4 when the parapet 2 is thick is placed on the parapet 2 as shown in FIG. A horizontal arm 6 protruding outward from the outer wall surface 3 is fixed to the stabilizer 5 by welding or the like, and a strut 7 is provided at the rear end of the arm 6. Are welded.

[0005] In use, the stabilizing plate 5 of the rope supporting device 4 is arranged so as to abut on the upper end corner of the parapet 2, and then the retaining rope 8 is wrapped around the base of the support 7 and the parapet 2 is wrapped around the parapet 2. On the other hand, the suspension wire rope 10 for suspending the work gondola 9 is connected to and fixed to the mounting rope 11 wound around the structure via the tip of the arm 6 and the upper end of the column 7.

A rope supporting device (usually referred to as a free hook) 12 in a case where the parapet 2 is relatively thin and can fix the parapet 2 from inside and outside is shown in FIG.
As shown in FIG. 2, a horizontal arm 13 mounted on the parapet 2 and protruding outward from the outer wall surface 3 is provided, and a front support member 14 provided with a reinforcing diagonal member below the outer wall surface 3 of the arm 13 is provided. Is applied to the outer wall 3 while the front support member 14 and the parapet 2 are sandwiched therebetween, and the rear support member 16 is slidably mounted on the arm 13. ing.

[0007] In use, the parapet 2 is positioned between the front support member 14 and the rear support member 16 of the arm 13 of the rope support device 12, and the pad 1
The arm 13 is arranged so that the strut 5 hits the outer wall surface 3, and the hanging wire rope 10 for hanging the work gondola 9 is connected to the upper part of the rear support member 16 via the tip of the arm 13, and the hanging wire rope 10 is connected to the arm 13.
